The cashier walked over to a desk, picked up a slip of paper, referred to it and said:

“They were from 177865B to 177870B.”

“Keno!” Carter shouted. He held in his hand the note which Rich had given to the cabman. He was looking at it when the cashier read the numbers.

“What is the matter?” the cashier asked.

“Do you see this bill?” Carter said, as he held the bill out for the cashier to inspect.

“Gracious! Captain, that note is numbered one hundred and seventy-seven thousand eight hundred and sixty-nine B! That is one of the bills which I gave to Mr. Lawrence!”

“Will you swear to that?”

“I will. That is one of the bills.”

“Thank you.”

The two men were silent.
